mo-vector

0.1.13 verified Fri May 01 auth: no python

mo-vector is a Python library providing efficient vector operations and support for vector data structures, built on top of mo-libs. The latest version is 0.1.13, with a focus on numerical computing and data manipulation. Development is active, with releases on PyPI.

pip install mo-vector

Common errors

error ModuleNotFoundError: No module named 'mo' ↓

cause Importing using incorrect dotted path instead of underscore.

fix

Install mo-vector and use from mo_vector import vector.

error TypeError: 'vector' object does not support indexing ↓

cause Attempting to index a vector like a list.

fix

Use .values attribute or list(vector) to get indexable object.

error AttributeError: 'list' object has no attribute 'dot' ↓

cause Trying to call .dot() on a Python list instead of a mo_vector object.

fix

Convert the list to a vector: vector(mylist).dot(other_vector).

Warnings

breaking Version 0.1.0 changed the import structure from dot-separated packages to underscores. Old imports like `from mo.vector import vector` will break. ↓

fix Use `from mo_vector import vector` instead.

deprecated The `vector` class's `__add__` method previously returned a new list. As of 0.1.10, it returns a `vector` object. Code relying on list output may break. ↓

fix If you need a list, call `list(result)` explicitly.

gotcha Vector operations (addition, multiplication) are element-wise by default, not matrix multiplication. Use `@` operator for dot product if available, or `.dot()` method. ↓

fix Use `v1 @ v2` or `v1.dot(v2)` for dot product.

Quickstart

Basic usage of mo-vector: creating vectors and performing operations.

from mo_vector import vector

# Create a vector
v = vector([1, 2, 3])
print(v)  # Output: [1, 2, 3]

# Vector operations
v2 = vector([4, 5, 6])
print(v + v2)  # Addition
print(v * 2)   # Scalar multiplication

# Dot product
print(v.dot(v2))
